3 SHEETS-SHEET 2- UNITED STATES PATENT cnr-ionl MICHAELJ. -IDENDINGER, OF RAIPID CITY, ,SUTH DAKOTA.

To all whomfz't may concern; Be it known that I, MICHAEL J.- DEN- DINGER, a citizen ofthe United States, re-

siding at Rapid City, inthe county of Pennington and vState of South Dakota, have in-` vented certain new and useful Improve-` ments in Hay-Stackers, of which the'pfollowing is al specification. .f i p i My ini'fention relates'to improvements 1n elevators or `stackers for hay orthe like, of-

the general type that embody an' inclined trough or chute, with a member, suchfas a rake', to-engage the hay and effect its travel upthe inclined trough or chute.

An important object of the invention is to provide means forV locking V'the carriage which travels longitudinally of the inclined chute, in the lowermost position, until the movable rake connectedv therewith has been brought into proper engagement'with the liayor the like.

A further object of my invention is to provide apparatusvof the above mentioned character, which is -simple in construction, inexpensive to manufacture, strongk and durable. i

Other objects and advantages lof the invention will be apparent during the course of the following description.

Inthe accompanying 'drawings forming `a part of this specification andin which like numerals are employed to designate parts throughout the same,

Figure 1 is aside elevation of apparatus r embodying my invention, i

Fig. 2 is an enlarged side elevation of the vertically movable rake and'associated elements,

Fig. 3 is a'y transverse sectional view takenVV on line 3-3 of Fig. 1,

Fig. 4 is an enlarged detail vertical section taken-on line of Fig. 2, and,

Fig. 5 is a plan view yof the apparatus. In the drawings, wherein for the purpose of illustration is shown va `preferred embodi- A ment of my invention, a wheeled supporting frame is shown,comprising lower horizontal longitudinal beams 10,'to the opposite ends of which are pivotally connectedfwheels 11 and 12.V Rigidly connected'with'the,longif tudinal beams 1 0 near their'ends are upwardly projecting inclined Vstandards 13, 14, Y,

land 16. v I y The apparatus further comprisesan 1nclined trough or chute, designated as a whole. by the' 'numeral 17. "This inclined chute'A like HAY-Macken.

comprises lower inclined rails 18, rigidly connected at their lower ends with the beams 10,-as show-nat 19, and rigidly connected clined chute are formed of longitudinal slats l 23,v secured at their lower ends to the standard 14 and -attheir upper ends to a bar 24. f

'- These slats mayalso be secured to the standj ard 15. Y

The upper 'end of the bottom of the chute 17 is preferably shortened and is'provided withva swinging bottom-extension 25, hinged'- thereto, as'shown at 26. This bottom-extension has pivotal connection at its forward end, as shown at 27, `with bars 28, provided with recesses or notches29, to receive therein Y stops or'lugs 30, rigidly securedV to the standards 16. It is thus apparentV that the eXten sion 25'may -be locked in the upper-"p04 sition. thereby forming an extension forthe bottom of the inclinedchute ormay assume an inclinedv position, as indicated by the dotted lines. Y'

Arranged at the rear'ends of the beams 10 and near the lower kor take-up end of the Vso inclinedchute 17 isfa supporting rack 28, comprising spaced longitudinaltines 30, rigidly Vsecured to ytransverse bars 31 and 32.'

The transverse bar 31rv is pivotally connected with the rear ends of the beams 10 by hingesv 33. It is thus apparent that the hay delivered upon'the supporting rack 28`may be f moved forwardly thereon-and be into the inclined chute 17. Y

The numeral 34 (see more particularly Figs.l 1, 2 and 4) designates upper inclined side rails, which arel rigidly secured to the upper ends of the standards 14 and v15 and to the bar 24. vThe rails 34 project, at their upper ends, beyond the inclined chute, for a substantial distance. At their lower ends,

the rails 34 have connection with rail exten-V sions 35, extendingV substantially parallel with the supporting rack 30. The rail eX- tensions 35 are'rigidly connected with the upper ends of the standards 13.

Arranged'inwardly of and extending longitudinally of the rails 34 and their lower discharged y extensions 35 are track rails 36, provided upon their outer `sides with attaching -members 37' (See rig. 5), which are* rigidly sie: cured to the rails 3i and their extensions.

These track rails36 vconform toithersh'a'pe` or inclination of the rails 34 and their eXtensions 35, as shown. l

Adapted to travel longitudinally of the;` tracltfrails 36 rand arrai'iged' therebetweenis" a carriage 37', preferably formed of anV open-work construction, embodying upstandl ing-corner posts. 38, rigidly connected` by,V diagonal braces 39. The cornerposts V38 of thecarriage, at one*V end, are rigidly con-V nectedcwith the corner posts at they other end, by longitudinal beams .40,Ywhi1ch are in turnrigidly connected bydiagonal braces 4l,- The lovelelids. of the POStSBS, are comYY nected by transverse. beams ,12,and the bot-y tomofithe ,frame 37 isforined' open, thus in no wayV interfering,` with the accumulation of hayuponthe supporting rack. Y Y

1s Alfnore clearly shown' in Figs. 2 and 4,' thefcorn'cr posts 38 carry upper andlower studs li3 and-Lupenwhich are rotatably mounted grooved wheels t5, operating above and lbelowthe track rails 36, as clearly illustrated in Fig. 4f.: Itis thus apparentthat the carriage 37 is'adapted ,to traveldongitudi- Y nally of and upon the tracl rails 36.

The nuineralll designates a preferably Y vertically swinging hay engagingmember, preferably inthe forni of a rake. This rake comprises endj levers or bars 46, having openings: arranged near and. spac'e'drfrom their forward endsfor receiving the studs' 43, whereby theleversf46 are pivotally connectedl with-,the carriage 37, toswingin a substantially verticalvplane. The rearends Y of the levers 46 are connected by atrans`- versebar ttolwhich are secured downwardly.extendingitines e8. The levers 1,6 aregswung upwardly by means of retractile springs 49,v secured thereto and tothe-carriage 3T. `The lewers '36 are provided at theirforwardends withl downwardly ein' tending cranks 5.0lizwing4 connection with elements 51, which maybe cables,A rods or the' like', havingI their forward ends connected Y with a'V transverse tubular Yequalizing Y, device cured ,to the transverse `bar 58.
